Abstract (en)
[origin: WO2020075048A1] An apparatus includes a dispersive-collimating element, a Faraday material apparatus and a focusing-dispersive element. The dispersive-collimating element assigns each beam wavelength to a particular spatial position. The beams are parallel one to the other. The Faraday material apparatus provides a polarization rotation independently for each wavelength, and the focusing-dispersive element recombines the different wavelengths into one single beam.
